Can I have two Cash ISAs in the same tax year UK?

You can open ONE of each ISA type per tax year. So you can't open two Cash ISAs with different providers in the same year. But you can have a Cash ISA AND a Stocks & Shares ISA in the same year, as they're different types.

Can I have multiple ISAs from previous years?

Yes — you can hold ISAs opened in previous tax years with different providers. The 'one per type per year' rule only applies to opening new ISAs. Your old ISAs continue, and you can have many Cash ISAs from different years.

Can I split my ISA allowance between providers?

Yes — you can split your £20,000 between different ISA types and providers. For example: £10,000 in a Cash ISA with one bank, and £10,000 in a Stocks & Shares ISA with another. But only one Cash ISA opened that tax year.

Can I transfer my ISA to get a better rate?

Yes — you can transfer ISAs between providers at any time without affecting your allowance. Use the official transfer process (don't withdraw). Transferring current year's ISA keeps it in current year; previous years' ISAs transfer tax-free.
